The two-day, much-ballyhooed Nuclear Security Summit (NSS) in the Netherlands, which concluded Tuesday, was politically haunted by the upheaval in Ukraine - the former Soviet republic that renounced some 1,800 of its nuclear weapons in one of the world's most successful disarmament exercises back in 1994.

Every nation in the world has been invited to participate at the highest political level in the High-Level Meeting of the General Assembly on Nuclear Disarmament scheduled for Sep. 26. This has never happened before. We have never been at such a moment of crisis and opportunity.

When the 193-member U.N. General Assembly (UNGA) holds is first-ever high-level meeting on nuclear disarmament next September, there is little or no hope that any of the nuclear powers will make a firm commitment to gradually phase out or abandon their lethal arsenals.
